Estimated P. vivax population structure by STRUCTURE software. Panel A represents the STRUCTURE results for the whole dataset, showing two peaks at K = 3 and 6 (delta K = 6 and 8.8). Panel B contains the bar plot at K = 3 and K = 6 with each sample being represented by a single vertical line divided into K colors, where K is the number of populations assumed. Each color represents one population, and the length of the colored segment shows the estimated proportion of membership of that sample to each population. Sample number 1-31 belong to population C, 32-70 to population B, 71-85 to population A1, and 86-94 to population A2.
